Side Impact Occupant Modeling Practices in Comparison to Test Results

A methodology to obtain and estimate the second row dummy response during the FMVSS 214 Barrier Side Impact test is described. Because of the limited amount of space between the occupant and the car structure, it is challenging to manage and predict the energy distribution in the FMVSS 214 crash mode. Increasing use of Finite Element models provides an edge in product development and its use is increasing as development time is reducing. For increased correlation with the test and more realistic dummy response, several factors are important, including the effect of restraint systems and representation of interacting components. This paper describes a methodology by which the second row occupant injury can be well-correlated to the test and used to help enhance occupant protection during vehicle development. A commercially available SID-IIs dummy and a Moving Deformable Barrier from LSTC are used in this study.
